In computing, multitasking is the concurrent execution of multiple tasks over a certain period of time. New tasks can interrupt already started ones before they finish, instead of waiting for them to end. As a result, a computer executes segments of multiple tasks in an interleaved manner, while the tasks share common processing resources such as central processing units (CPUs) and main memory. Multitasking automatically interrupts the running program, saving its state and loading the saved state of another program and transferring control to it. This "context switch" may be initiated at fixed time intervals, or the running program may be coded to signal to the supervisory software when it can be interrupted.
In computing, a context switch is the process of storing the state of a process or thread, so that it can be restored and resume execution at a later point, and then restoring a different, previously saved, state. This allows multiple processes to share a single central processing unit (CPU), and is an essential feature of a multiprogramming or multitasking operating system. In a traditional CPU, each process - a program in execution - utilizes the various CPU registers to store data and hold the current state of the running process. However, in a multitasking operating system, the operating system switches between processes or threads to allow the execution of multiple processes simultaneously. For every switch, the operating system must save the state of the currently running process, followed by loading the next process state, which will run on the CPU. This sequence of operations that stores the state of the running process and the loading of the following running process is called a context switch.
The terms foobar, foo, bar, baz, and others are used as metasyntactic variables and placeholder names in computer programming or computer-related documentation. They have been used to name entities such as variables, functions, and commands whose exact identity is unimportant and serve only to demonstrate a concept. The style guide for Google developer documentation recommends against using them as example project names because they are unclear and can cause confusion.
A real-time operating system (RTOS) is an operating system (OS) for real-time computing applications that processes data and events that have critically defined time constraints. An RTOS is distinct from a time-sharing operating system, such as Unix, which manages the sharing of system resources with a scheduler, data buffers, or fixed task prioritization in a multitasking or multiprogramming environment. Processing time requirements need to be fully understood and bound rather than just kept as a minimum. All processing must occur within the defined constraints. Real-time operating systems are event-driven and preemptive, meaning the OS can monitor the relevant priority of competing tasks, and make changes to the task priority. Event-driven systems switch between tasks based on their priorities, while time-sharing systems switch the task based on clock interrupts.
An adjective is a word that describes or defines a noun or noun phrase. Its semantic role is to change information given by the noun.
In computing, a process is the instance of a computer program that is being executed by one or many threads. There are many different process models, some of which are light weight, but almost all processes are rooted in an operating system (OS) process which comprises the program code, assigned system resources, physical and logical access permissions, and data structures to initiate, control and coordinate execution activity. Depending on the OS, a process may be made up of multiple threads of execution that execute instructions concurrently.
Archie Goodwin is a fictional character in a series of detective stories and novels by American author Rex Stout. Archie is the witty narrator of the cases featuring his boss, Nero Wolfe, from 1934 (Fer-de-Lance) to 1975. Although his job title is Wolfe's secretary and chauffeur, Archie is effectively Wolfe's partner in the detective business, and the stories often contrast his middle class streetwise persona with Wolfe's aristocratic intelligence.
In military operations, military reconnaissance or scouting is the exploration of an area by military forces to obtain information about enemy forces, the terrain, and civil activities in the area of operations. In military jargon, reconnaissance is abbreviated to recce and to recon, both derived from the root word reconnoitre.
Ad hoc is a Latin phrase meaning literally 'for this'. In English, it typically signifies a solution for a specific purpose, problem, or task rather than a generalized solution adaptable to collateral instances.
Morale, also known as esprit de corps, is the capacity of a group's members to maintain belief in an institution or goal, particularly in the face of opposition or hardship. Morale is often referenced by authority figures as a generic value judgment of the willpower, obedience, and self-discipline of a group tasked with performing duties assigned by a superior. According to Alexander H. Leighton, "morale is the capacity of a group of people to pull together persistently and consistently in pursuit of a common purpose". Morale is important in the military, because it improves unit cohesion. With good morale, a force will be less likely to give up or surrender. Morale is usually assessed at a collective, rather than an individual level. In wartime, civilian morale is also important. Esprit de corps is considered to be an important part of a fighting unit.
The estimated time of arrival (ETA) is the time when a ship, vehicle, aircraft, cargo, person, or emergency service is expected to arrive at a certain place.
In concurrent programming, a monitor is a synchronization construct that prevents threads from concurrently accessing a shared object's state and allows them to wait for the state to change. They provide a mechanism for threads to temporarily give up exclusive access in order to wait for some condition to be met, before regaining exclusive access and resuming their task. A monitor consists of a mutex (lock) and at least one condition variable. A condition variable is explicitly 'signalled' when the object's state is modified, temporarily passing the mutex to another thread 'waiting' on the conditional variable.
Cut and run or cut-and-run is an idiomatic verb phrase meaning to "make off promptly" or to "hurry off". The phrase was in use by the 1700s to describe an act allowing a ship to make sail quickly in an urgent situation, by cutting free an anchor. Though initially referring to a literal act, the phrase was used figuratively by the mid-1800s in both the United States and England. The phrase is used pejoratively in political language, implying a panicked and cowardly retreat, and it has been used by politicians as a criticism of calls to withdraw troops from various armed conflicts, becoming particularly associated with the Iraq War and with the diction of the United States Republican Party. It has also been used in other contexts, such as in World War II military slang and to refer to a container shipping practice.
In computer science, synchronization is the task of coordinating multiple of processes to join up or handshake at a certain point, in order to reach an agreement or commit to a certain sequence of action.
A moron in a hurry is a phrase that has been used in legal cases, especially in the UK, involving trademark infringement and passing off. Where one party alleges that another has infringed their intellectual property rights by offering for sale a product that is confusably similar to their own, the court has to decide whether a reasonable person would be misled by the defendant's trademark or the get-up of their product. It has been held that "if only a moron in a hurry would be misled" the case is not made out. Although this formulation addresses only fairly extreme instances of confusibility, and says nothing about less clear examples, the phrase is sometimes referred to as a "test".
Fixed-priority preemptive scheduling is a scheduling system commonly used in real-time systems. With fixed priority preemptive scheduling, the scheduler ensures that at any given time, the processor executes the highest priority task of all those tasks that are currently ready to execute.
"Hurry Up and Wait" is a song by Welsh rock band Stereophonics, released as the fifth and final single from their second album, Performance and Cocktails (1999), on 8 November 1999. The song reached number 11 on the UK Singles Chart, as did previous single "I Wouldn't Believe Your Radio". It also reached number 23 in Ireland, becoming the band's fifth top-30 hit there.
Mednyj Aleut is an extinct mixed language spoken on Bering Island.
Festina lente or speûde bradéōs is a classical adage and oxymoron meaning "make haste slowly". It has been adopted as a motto numerous times, particularly by the emperors Augustus and Titus, then later by the Medicis and the Onslows.
Hurry Up and Wait is the third studio album by Australian rock band Dune Rats. It was released on 31 January 2020. The album was supported with an Australian tour between February and March 2020.
